Chromaticity Standard Deviation (SDC) indicator

•Longman was the first in the world to propose a quantitative method for assessing the uniformity of color mixing - Chromaticity Standard Deviation, abbreviated as SDC. SDC stands for Standard Deviation of Chromaticity., especially for the led lighting products. Generally, a range of 0-0.005 indicates that the color mixing is suitable for stage lighting fixtures, 0.005-0.01 indicates that the color mixing is slightly poor and can be distinguished by the naked eye. An indicator greater than 0.01 signifies that the light fixture's color mixing is extremely poor.
